Abstract: A battery powered fluid sprayer includes a shelter that the battery is mounted in to provide power to the electric components of the sprayer. The shelter protects the battery from falling fluid droplets. The shelter extends above the battery and projects outward laterally and longitudinally to protect the battery. The battery can move vertically downward to dismount from the fluid sprayer.

Abstract: A battery powered fluid sprayer includes a battery mounted to a vertically extending wall of the fluid sprayer. The battery powers an electric motor to power a pump to pump fluid to a spray gun for spraying. The battery is disposed within a battery chamber enclosed by a door. The battery is suspended above a base of the battery chamber to isolate battery from any fluid that may enter the chamber.

Abstract: A method of displacing fluid includes pulling a pump displacement member through a suction stroke with a pull, the pull configured to transmit only tensile forces to the fluid displacement member. A working fluid disposed in an internal pressure chamber drive the fluid displacement member through a pumping stroke. The pull is prevented from transmitting any compressive forces to the fluid displacement member, such that the pull does not drive the fluid displacement member through the pumping stroke.
